Maybe the company realises that if you keep this up you're going to quit (or your friends and family are going to be VERY STRONGLY urging you to quit) and they obviously need you.

Or maybe they just realise that you have a strong enough work ethic that working from home shouldn't be a problem.

_{following on from my reply to your previous comment, stop working when you hit your stop work time, finish the task you're on if you absolutely have to but absolutely under no circumstances pick up another task no matter how quick it looks}

Enjoy your trip :D
